CH4 - methane

This data point measures the total direct methane (CH₄) emissions from industrial processes only during the reporting year, expressed in metric tonnes (t). Methane is a potent greenhouse gas, and in this context, emissions result from process-related activities — not from fuel combustion in stationary or mobile sources.

Examples include methane released during chemical production, waste processing, or certain metallurgical processes. This is reported separately from CH₄ emissions from combustion, which are covered in other data points.

What to include:

  • CH₄ emissions from industrial processes only, such as:

    • Petrochemical production

    • Certain mineral processing activities

    • Waste treatment processes under direct company control

    • Metallurgical operations where methane is a byproduct

  • Only emissions from owned or controlled facilities

  • Measured directly or calculated from process activity data × recognised emission factors

What not to include:

  • CH₄ from stationary combustion of fuels (boilers, generators)

  • CH₄ from mobile combustion (company vehicles, machinery)

  • CH₄ from agricultural activities not part of industrial processes

  • Fugitive emissions from pipelines or storage tanks (reported separately if applicable)

Estimation Methodology:

  • If full-year process emission data is unavailable:

    • Gather actual monitored data for available months

    • Calculate the monthly average

    • Multiply by the number of missing months

    • Apply process-specific emission factors if data is in terms of production volumes

    • Clearly note the estimated portion in your records
